Ultimaton, an experimental electro-acoustic album featuring prepared piano and Kyma X processing, was released in December 2012 by Jorge Lima Barreto (piano & percussion) and Jonas Runa (Kyma X).

Zul Zelub (zul = luz or light, zelub = Boulez) is described as unrealized musical energy, the unexpressed, the force which does not generate matter, a virtual formulation as in a dream or a cyber journey.

Barreto’s piano performance is an experimentalist improvised flow, unfolding in various concepts and dynamics of time (slowed-down or accelerated, asynchronous and synchronous) creating new sound spaces. Digital musician and composer João Marques Carrilho (aka Jonas Runa) captures, interferes, superimposes timbres, and participates in a real-time musical conversation with the piano.

The duo explores the questions: What lies behind an act of musical creation? What precedes it? What enables its actualization in sound?

To Barreto and Runa, musical improvisation is a living force that induces an action and maintains a momentary state of the body. “Improvisation lives in the unknown, at the mercy of the Creative Energy and Open Form; in it’s aesthetic stance, improvisation is possibility and performance (corporal action) – it is an ephemeral state pointing to the unrealized.”

Ultimaton is available as an immediate download or in a limited edition cardboard double-sleeve wallet that includes photographs and background on the project and its creators.
